    Choose PETG when…

    • Containers, bottles, and organizers
    • Brackets and parts that flex without cracking
    • Food-contact parts (with a food-safe finish)
    • Parts that need water and chemical resistance

    Reach for something else for

    • Ultra-fine detail display models — PLA prints crisper

    Choose Nylon when…

    • Living hinges
    • Gears and bushings
    • Low-friction moving parts
    • Parts that flex repeatedly

    Reach for something else for

    • High-detail cosmetic parts — PLA is crisper and cheaper
